The Ennio Morricone music reflect the noir atmosphere of the plot where a veritable subtle "manhunt" against three people is unleashed . Suspense music on the border of the avant-garde experiments (harps with echoes) is alternated to a nostalgic motif with the voice of Edda Dell'Orso. At the time, only a 45 rpm was issued in Italy. Mastered from the original stereo master tapes.
